SIDING PANEL ASSEMBLY
Field
[0001] Aspects of the present disclosure are directed to a siding
panel, and
more particularly to a low-profile siding panel with improved properties
including low
thermal expansion, fire performance, impact resistance, and workability.
Description of the Related Art
[0002] Siding, or wall siding, is commonly used to cover the
exterior surfaces,
e.g. walls, of structures. Such siding is often formed of metal, such as
aluminum, or
thermoplastic materials, such as polyvinyl chloride (PVC). Siding installed on
vertical
surfaces may be formed with one or more sections or courses. Such siding is
typically
installed in multiple rows of panels, with each row overlapping the panels to
which it is
adjacent. Adjoining panels are overlapped in this manner to provide protection
for the
structure from the weather.
[0003] Existing siding panels are limited in the length of the face
or course of
the panel. Additionally, siding panels made of thermoplastic materials (such
as PVC)
typically have a curved (e.g., non-planar) face.
SUMMARY
[0004] Accordingly, there is a need for improved materials and
improved
siding panel designs.
[0005] In accordance with one aspect of the disclosure, a siding
panel is
provided with improved resistance to thermal expansion. In one implementation,
siding
panels disclosed herein have a coefficient of linear thermal expansion (CLTE)
lower than
that of conventional vinyl siding. In one implementation, the siding panels
disclosed
herein have a CLTE approximately 1/3 lower than that of conventional vinyl
siding.
[0006] In accordance with another aspect of the disclosure, a
siding panel is

DETAILED DESCRIPTION
Siding Panel
[0034] FIGS. 1-7 show a siding panel assembly 100 having a siding
panel 10
and a backing panel 50. Optionally, the siding panel 10 can be defined by a
single
continuous sheet of material (e.g., monolithic, single piece, without seams).
Optionally,
the siding panel 10 can be made of a thermoplastic material. In one
implementation, the
siding panel 10 can be made of a composite material that includes the
thermoplastic
material. Optionally, the siding panel 10 can be made of a material that
includes a
polyvinyl chloride (PVC) resin. The composition of the siding panel 10 is
further
discussed below.
[0035] The siding panel 10 can include a course or face portion 12
with a
forward facing (e.g., outer facing) surface 12a and a rearward facing (e.g.,
inner facing)
surface 12b that extends from an upper end 14 to a lower end 16.
Advantageously, the
course or face portion 12 is substantially planar (e.g., along its entire span
between the
upper end 14 to the lower end 16). In one implementation, the course or face
portion 12 is
flat and presents a flat forward-facing surface 12a, advantageously providing
an improved
appearance (e.g., approximating that of wood or fiber cement siding).
-5-
CA 3067803 2019-11-29
[0036] Advantageously, the siding panel assembly 100 has a low
profile. In
one implementation, the siding panel assembly 100 has a maximum thickness H
from a
rear surface 52 of the backing panel 50 to the front facing surface 12a of the
siding panel
of no more than approximately 0.7 inches, such as 0.72 inches. In one
implementation, said maximum thickness is between about 1/2 inches and about
3/4 inches.
That is, the siding panel assembly 100 projects from the mounting surface
(e.g., from the
backerboard) no more than approximately between 1/2 inches and 3/4 inches,
such as
approximately 0.7 inches, which facilitates the installation of the siding
panel assembly
100, as further described below.
[0037] Optionally, one or both ends of the siding panel 10 can have
an
overhang portions 17 (that define end notches 17') that extends past the edge
of the
backing panel 50 and past the nail hem 40. As discussed further below, in one
implementation, the overhang portions 17 of adjacent siding panels 10 can
overlap. In
another implementation, only one end of the siding panel 10 has the overhang
portion 17
(or notch 17'), and during installation, the overhang portion17 of one panel
10 extends
over a straight cut end of an adjacent panel 10. In another implementation,
the siding
panel 10 does not have such overhang portions 17 (i.e., the siding panel 10
has a straight
cut at the left and right end of the panel where the edge of the siding panel
10 generally
aligns with the edge of the backing panel 50 and the edge of the nail hem 40).
[0038] In some implementations, the overhang portion 17 (and notch
17') has
a width L3 of between approximately 1/2 inches to 1 1/2 inches, such as
between
approximately 1/2 inches to 1 'A inches. In some implementations, the overhang
portion 17
(or notch 17') has a width L3 of approximately 0.75 inches (e.g., the edge of
the backing
panel 50 is set back about 0.75 inches from the edge of the panel 10), which
advantageously reduces the amount of the panel 10 that is not supported by the
backing
panel 50, resulting in advantages during installation and use, as further
described below.
For example, reducing the width L3 of the overhang portion 17 to approximately
0.75
inches advantageously aids the siding panel assembly 100 in maintaining the
planar (e.g.,
flat) appearance when overlapped with adjacent siding panel assemblies 100. As
discussed further below, the reduction in the width L3 of the overhang portion
17 (and
notch 17') is facilitated at least in part by the thermal expansion
performance of the siding
panel assembly 100. An upper or proximal edge of the overhang portion 17 can
be spaced
from the proximal edge 46 of the nail hem 40 by a distance 47. In some
implementations,
-6-
CA 3067803 2019-11-29
the distance 47 can be between about 0.5 inches and about 1.5 inches, such as
about 1.0
inches. During installation of the siding panel assembly 100 adjacent a second
siding
panel assembly 100, the backing panel of the second siding panel assembly
extends into
the space or notch 17' under the overhang portion 17, and the overhang portion
17 of the
siding panel assembly 100 overlaps with the siding panel 10 of the second
siding panel
assembly 100.
[0039] The siding panel 10 can have a thickness t of between about
0.040
inches and about 0.050 inches, such as approximately 0.048 inches. Optionally,
the
siding panel 10 can have a substantially uniform thickness (e.g., a constant
thickness)
along its entire span between the upper end 14 and the lower end 16). In other
implementations, the thickness t of the siding panel 10 can be lower toward
the edges of
the panel 10.
[0040] The siding panel 10 can include one or more substrate layers
11A and
one or more capstock layers 11B (e.g., weatherable layers). In one
implementation, the
one or more capstock layers 11B can have a thickness t2 of between about 0.004
inches
and about 0.006 inches. In one implementation, the one or more substrate
layers 11A can
have a thickness ti equal to the difference between the thickness t of the
siding panel 10
and the thickness t2 of the capstock layers 11B, such as of about 0.034 inches
and about
0.044 inches. Discussion of the materials of the siding panel 10 is provided
further below.
[0041] In one implementation, the course or face portion 12 can
have a length
L between the upper and lower. ends 14, 16 of approximately seven inches. In
another
implementation, the course or face portion 12 can have a length L between the
upper and
lower ends 14, 16 of approximately five inches. In still another
implementation, the
course or face portion 12 can have a length L between the upper and lower ends
14, 16 of
between about four inches and about twelve inches, such as about five inches
or six
inches. However, the face portion 12 of the panel 10 can have other suitable
lengths L
that are greater or smaller than those provided above. The siding panel 10 can
have a
length L' between the upper and lower ends 14, 16 that is greater than the
length L of the
course portion 12. The length L' can be between about five inches and about 14
inches,
such as about 7.5 inches. However, the siding panel 10 can have other suitable
lengths L'
that are greater or smaller than those provided above. The siding panel 10 can
have a
length L" between a proximal edge 46 of a nail hem 40 and the lower end 16
that is
greater than the length L'. The length L" can be between about six inches and
about 15
-7-
CA 3067803 2019-11-29
inches, such as about 8.25 inches. However, the siding panel 10 can have other
suitable
lengths L" that are greater or smaller than those provided above.
[0042] The siding panel 10 can have a lock portion 20 attached or
connected
to the upper end 14 of the course portion 12 and a buttlock portion 30
attached or
connected to the lower end 16 of the course portion 12.
[0043] The lock portion 20 can include a U-shaped wall portion 22
that
defines an upward facing channel 22a having a width 22b. The U-shaped wall
portion 22
can be connected to the course portion 12 by a U-shaped wall portion or tongue
portion
24 that defines a downwardly facing channel 24a having a width 24b.
Optionally, the
width 22b is greater than the width 24b. The U-shaped wall portion or tongue
portion 24
can have a bulbous portion 24C (e.g., that curves outward relative to a
'straight plane), that
facilitates locking the tongue portion 24 in a buttlock portion 30 of an
adjacent siding
panel assembly 100.
[0044] The buttlock portion 30 can include a U-shaped wall portion
32 that
defines a downward facing channel 32a having a width 32b. Optionally, the
width 32b is
greater than the width 24b, such that the downward facing channel 32a of the
buttlock
portion 30 of one siding panel 10 fits over and receives the U-shaped wall
portion 24 of
an adjacent siding panel 10. Optionally, a wall segment 32c of the U-shaped
wall portion
32 extends at an angle 32d such that the wall segment 32c is not parallel to
the opposite
wall segment of the U-shaped wall portion 32 so that the downward facing
channel 32a
tapers toward its open end. The angle 32d can be between about 3 degrees and
about 10
degrees, such as about 5 degrees. Advantageously, such a tapered channel 32a
can
resiliently fit over the U-shaped wall portion or tongue portion 24 to more
securely (e.g.,
rigidly) couple one siding panel 10 to another siding panel 10, and avoid slop
(e.g., play)
between the tapered channel 32a and the U-shaped wall portion 24 to thereby
avoid
rattling of one panel 100 relative to an adjacent panel 100 below it (e.g.,
when the panels
100 are exposed to wind once installed). The tapered channel 32a also allows
the wall
segment 32c to clear the nail head of the nail on the nail hem 40 of an
adjacent panel 100.
[0045] The U-shaped wall portion 32 can be connected to the lower
end 16 of
the course portion 12 by a base portion 34 having a width 34a. The U-shaped
wall
portion or lock 32 can have a depth D of between about 0.40 inches and about
0.50 inches
(e.g., 0.50 inches) that receives the U-shaped wall portion or tongue portion
24 of an
adjacent panel assembly 100. Optionally, the width 34a is greater than the
width 24b.
-8-
CA 3067803 2019-11-29
Optionally, the width 22b is greater than the width 24b. One or more weep
slots 36 can be
formed in the base portion 34. Advantageously, the coupling of the tongue
portion 24 and
buttlock portion 30 (e.g., the bulbous portion 24C of the tongue portion 24
with the lock
32) provides a resilient connection between adjacent panel assemblies 100 that
resulted in
improved windload performance, which is discussed further below. Additionally,
the
coupling between the tongue portion 24 and the lock portion 32 of adjacent
siding panel
assemblies 100 can inhibit flame spread between adjacent panel assemblies,
resulting in
improved fire performance for the panel assembly 100.
[0046] The siding panel 10 can also include a nail hem 40. The nail
hem 40
can include a substantially planar wall (e.g., a flat wall) 42 that extends
from (e.g., is
integrated with) the U-shaped wall portion 22 that defines the upwardly facing
channel
22a to a proximal edge 46 (e.g., nail hem 40 defined by a single wall 42). As
shown in
FIG. 1, the nail hem 40 is spaced behind the course portion 12 and extends
above the
upper end 14 of the course portion 12 (e.g., the proximal edge 46 extends past
the upper
end 14 of the course portion 12). Advantageously, the nail hem 12 is defined
by a single
wall that extends to the proximal edge 46, providing a lower profile nail hem.
Optionally,
the nail hem 40 can include a reinforcement strip 48 along at least a portion
of the span of
the nail hem 40. For example, in one implementation, the reinforcement strip
48 can
extend along some but not all of the span of the nail hem 40. In one
implementation, the
reinforcement strip 48 is made of a thermoplastic material (e.g., PVC). In one
implementation, the reinforcement strip 48 is embedded in the nail hem 40. In
another
implementation, the reinforcement strip 48 is attached to an outer surface of
the
substantially planar wall 42 of the nail hem 40. Optionally, the reinforcement
strip 48 can
be extruded and laminated onto the planar wall 42 of the nail hem 40. In
another
implementation, the reinforcement strip 48 can be adhered to (e.g., with an
adhesive) the
planar wall 42 of the nail hem 40. In another implementation, the
reinforcement strip 48
can be laminated and taped over the planar wall 42 of the nail hem 40. In one
implementation, the reinforcement strip 48 is approximately 0.015 inches
thick.
[0047] Advantageously, the reinforcement strip 48 allows the
reinforcement of
the nail hem 40 while maintaining a low profile for the nail hem 40, as
further discussed
below. For example, the nail hem 40 does not have a rollover portion (as
conventional
siding elements do), which allows the nail hem 40 to have a lower profile.
Having such a
low profile for the nail hem 40 allows the backing panel 50 to have additional
volume
-9-
CA 3067803 2019-11-29
(because the backing panel 50 does not have to be cut to accommodate a
rollover portion
of the nail hem of an adjacent siding panel assembly 100), resulting in a
siding panel
assembly 100 with a higher R value and improved noise insulation (e.g., noise
deadening)
properties. The lower profile also facilitates installation of the siding
panel assemblies
100, as further discussed below, by facilitating the coupling of the U-shaped
wall portion
32 of the buttlock portion 30 of one siding panel assembly 100 over the u-
shaped wall
portion 24 of the lock portion 20 in an adjacent siding panel assembly 100 in
a tongue-in-
groove manner, and by allowing the use of standard accessories (e.g., J-
channel or inside
and outside corner posts, etc.).
[0048] The nail hem 40 can have one or more openings (e.g., one or
more slot
openings) 49 therein, through which at least a portion of one or more nails
can be
inserted. Optionally, the openings 49 are defined through the reinforcement
strip 48 and
the substantially planar wall 42. Optionally, the one or more openings 49 can
be formed
using a rotary punch tool. However, the one or more openings 49 can be formed
in other
suitable manners. In one implementation, the one or more openings 49 can have
a length
Li of between about 1 inch and about 1.12 inches, and the spacing 49A between
the
openings 49 can be between about 0.48 inches and about 0.6 inches.
Advantageously, the
length Li of the one or more openings 49 and/or spacing 49A between the
openings 49
aids in improving the windload resistance of the siding panel assembly 100, as
discussed
further below. For example, the length Li of the one or more openings and/or
the spacing
49A between the openings 49 allow the siding panel assembly 100 to be more
securely
installed (e.g., by increasing the number of openings 49 on the nail hem 40
that can
receive nails during installation). As discussed further below, the increase
in the number
of openings 49 and/or reduction in the spacing 49A between openings 49 is
facilitated at
least in part by the thermal expansion performance of the siding panel
assembly 100.
=
= Backing Panel
[0049] With continuing reference to FIGS. 1-7, the backing panel 50
can have
a front surface 51 that extends from an upper end 53 to a lower end 54, a
shoulder or
ledge 55 at the upper end 53 and a rib 56 at the lower end 54. The backing
panel 50 can
optionally have a recessed portion 57 defined by surface 57a that is recessed
relative to
the rear surface 52 and proximate the lower end 54. The backing panel 50 can
extend
along a length L2 of between about 5 inches and about 8 inches, in one example
about 7
-10-
CA 3067803 2019-11-29
inches. However, the backing panel 50 can have other lengths L2 that are
greater or
smaller than those provided above. The rear surface 52 of the backing panel 50
substantially aligns with the substantially planar wall 42 of the nail hem 40
(e.g., so that
the rear surface 52 and nail hem 40 substantially extend along the same plane
or are
coplanar). The backing panel 50 tapers toward the upper end 53.
Advantageously, the
lower end 54 of the backing panel 50 extends to the lower end 16 of the siding
panel 10
(e.g., between the channel 32a and the rear facing surface of the siding panel
10). This
advantageously inhibits (e.g., prevents) the sinking of the panel 10 at the
lower end 16
(e.g., distal location of the siding panel 10 that is disposed over the nail
hem of an
adjacent siding panel assembly 100), for example when exposed to high
temperatures
(e.g., between 150 degrees F and 210 degrees F). Accordingly, the siding panel
assembly
100 provides support of the siding panel 10 by the backing panel 50 along the
length L of
the course or face portion 12 of the siding panel 10.
[0050]
Optionally, the backing panel 50 can be made of a closed cell or open
cell material. In one implementation, the backing panel 50 can be made of a
light-weight
foam material. For example, in some implementations, the backing panel 50 can
be made
of a PVC foam material. In another implementation, the backing panel 50 can be
made of
an expanded polystyrene (EPS) closed cell rigid foam insulation material
(e.g., having a
1.0 lb/ft3 density, having a 2.0 lb/ft3 density, etc.). In another example,
the backing panel
50 can be made of a graphite polystyrene (GPS) foam, such as NEOPOR by BASF,
which advantageously has higher fire resistance (e.g., GPS 2300 1.0 lb/ft3
density, GPS
2300 1.25 lb/ft3 density, GPS 2300 1.5 lb/ft3 density). In other
implementations, the
backing panel 50 can be made of GPS foam such as NEOPOR by BASF with extra
graphite (e.g., GPS 5200+ 0.85 lb/ft3 density, 5200+ 1.0 lb/ft3 density, GPS
5300+ 0.85
lb/ft3 density, GPS 5300+ 1,0 lb/ft3 density, GPS 5300+ 1.25 lb/ft3 density).
In still
another example, the backing panel 50 can be made of extruded polystyrene
(XPS) closed
cell rigid foam insulation material, which advantageously provides improved
rigidity. In
still another example, the backing panel 50 can be made of polyurethane foam
(e.g., 2.0
lb/ft3 density foam made by Jasper Plastics). In still other implementations,
the backing
panel 50 can be made of a foam with a density of between approximately 0.75
lb/ft3 and
approximately 2.10 lb/ft3. In still another implementation, the backing panel
50 can be
made of polypropylene. In another implementation, the backing panel 50 can be
a foil
backing (e.g., aluminum on either side of a paper core), which has an improved
fire rating
-11-
CA 3067803 2019-11-29
performance. Advantageously, the backing panel 50 can be rigid or
substantially rigid
and provides rigidity to the siding panel assembly 100 (e.g., when a user
presses against
the siding panel assembly 100 once installed on a wall). The backing panel 50
can have
an R value of 1.5 to 2.0, and facilitate the sound deadening qualities of the
siding panel
assembly 100.
Adhesive
[0051] The backing panel 50 can be attached to the siding panel 10.
For
example, the front surface 51 of the backing panel can be adhered (e.g., with
an adhesive)
to the rear facing surface 12b of the course portion 12, so that the shoulder
or ledge 55 is
adjacent (e.g., below) the U-shaped wall portion 22 of the lock portion 20 and
so that the
rib 56 is disposed between the rear facing surface 12b and the U-shaped wall
portion 32
of the buttlock portion 30 to facilitate retaining of the backing panel 50
within the
envelope of the siding panel 10. In one implementation, the backing panel 50
is adhered
to the rear facing surface 12b of the course portion 12 with a high
temperature adhesive,
such as a crosslinked polyurethane (PUR) adhesive. In another implementation,
the
adhesive can be a pressure sensitive adhesive (PSA). Optionally, the adhesive
can have a
thickness of between about 0.010 and 0.020 inches. Advantageously, adhering
the
backing panel 50 to the siding panel 10 aids in maintaining the siding panel
10 in a
substantially flat or planar shape, as well as in reducing the coefficient of
linear thermal
expansion (CLTE) of the siding panel assembly 100. In one implementation, the
adhesive
advantageously maintains adhesion between the siding panel 10 and the backing
panel 50
up to temperatures of approximately 180 deg. F to 210 deg. F (e.g., under
outdoor
exposure to sunlight or sunlight reflected onto panel assembly 100 from nearby
windows).
Composition
[0052] As discussed above, the siding panel 10 can have one or more
capstock
layers 11B and one or more substrate layers 11A. The capstock layer(s) 11B can
be
disposed over (e.g., cover the substrate layers 11 A (e.g., such that the
substrate layer(s)
11B are disposed between the capstock layer(s) 11B and the backing panel 50.
Optionally,
the one or more capstock layers 11B can be co-extruded over the one or more
substrate
layers 11A.
-12-
CA 3067803 2019-11-29
[0053] In one
implementation, the one or more capstock 'layers 11B can be
made of PVC. In another implementation, the one or more capstock layers 11B
can be
made of acrylonitrile-styrene-acrylate (ASA) material. In still other
implementations, the
capstock layer(s) 11B can be made of other suitable materials.
100541 The one or more
substrate layers 11A can be made of a reinforced
thermoplastic material. In one implementation, the thermoplastic material can
be vinyl
(e.g., Poly(vinyl chloride)). In other implementations, the thermoplastic
material can be
another polymer material (e.g., polypropylene, polyethylene, etc.). In
one
implementation, the thermoplastic material can be reinforced with high aspect
ratio fillers.
In one implementation, the .high aspect ratio fillers are randomly distributed
in the
thermoplastic material. In one implementation, the high aspect ratio fillers
include glass
fiber (e.g., reinforced glass fiber, fiberglass). In one implementation, the
fiberglass has an
aspect ratio of at least 10 to 1 at a loading of at least 5% (e.g., in an
amount of at least 5%
of the thermoplastic material composition). In one implementation, the
thermoplastic
material can additionally or Alternatively be reinforced with Wollastonite
(e.g., can be
made of glass fiber reinforced with Wollastonite) as the high aspect ratio
filler. In one
implementation, the Wollastonite fillers have an aspect ratio of at least 5 to
1 at a loading
of at least 10% (e.g., in an amount of at least 10% of the thermoplastic
material
composition). In still other
implementations, the thermoplastic material can be
reinforced with other materials (e.g., KEVLAR , carbon fiber, talc, etc.). In
another
implementation, the high aspect ratio fillers include talc and has an aspect
ratio of at least
to 1 at a loading of at least 10% .(e.g., in an amount of at least 10% of the
thermoplastic
material composition).
[0055] The
thermoplastic material of the substrate layer(s) 11A can include
one or more additives (e.g., fire retardant chemicals) to enhance the fire
resistance of a
panel assembly, such as the siding panel assembly 100, made with the
thermoplastic
material. In one implementation, the fire retardant chemical can be Zinc
Hydroxy
Stannate (ZHS). In another implementation, the fire retardant chemical can be
Zinc
Borate. In still another implementation, the fire retardant chemical can be
antimony. In
still another implementation, the fire retardant chemical can be Ammonium
OctaMolybdate. In still another implementation, the fire retardant chemical
can be a
Molybdate containing composition including Zinc Molybdate on Talc. However,
other
suitable fire or flame retardant materials can be used. In some
implementations, the fire
-13-
CA 3067803 2019-11-29
retardant chemical is provided in an amount of between about 0.5% and about 5%
of the
thermoplastic composition, such as the thermoplastic compositions (e.g., of
the
thermoplastic resin composition) disclosed herein.
[0056] The
thermoplastic material of the substrate layer(s) 11A can include
one or more additives (e.g., impact modifiers) to enhance the impact
resistance of a panel
assembly, such as the siding panel assembly 100, made with the thermoplastic
material.
In some implementations, the thermoplastic material composition (e.g.,
thermoplastic
resin composition) includes an impact modifier in an amount of between about
5% and
15% of the composition. In one implementation, the impact modifier is
Chlorinated
Poly(ethylene) or CPE impact modifier. In
some implementations, Chlorinated
Poly(ethylene) impact modifier is used in an amount of approximately 12% of
the
composition. In another implementation, the impact modifier is a cross-linked
Poly (butyl
methacrylate) with a Poly(methyl methacrylate) shell (e.g., an acrylic impact
modifier). In
some implementations, the acrylic impact modifier (e.g., a cross-linked Poly
(butyl
methacrylate) with a Poly(methyl methacrylate) shell) is used in an amount of
approximately 10% of the composition. In another implementation, the impact
modifier
is Butyl acrylate rubber core with a methyl methacrylate shell. In another
implementation,
the impact modifier is Methyl methacrylate Butadiene Styrene terpolymer.
However,
other suitable impact modifier materials can be used. Advantageously, the
impact
modifier can inhibit (e.g., prevent) crack propagation in the thermoplastic
material (e.g.,
in rigid poly(vinyl chloride)).
[0057] In
one implementation, the substrate layer(s) 11A can optionally
include a composite mixture including between about 0% and 20% glass fiber,
and
between about 0% and about 80% Wollastonite, with the remainder of the
substrate
layer(s) 11 A made up of other components, such as vinyl resin, impact
modifiers (e.g.,
acrylic impact modifier (AIM) or Chlorinated Polyethylene (CPE) impact
modifier),
lubricants, stabilizers, etc. Provided below are two examples of a composition
of the
substrate layer(s) 11A of a siding panel, such as the siding panel 10, where
PHR is parts
per hundred resin.
[0058] In
some implementations, the composition can include an impact
modifier in an amount that is between about 5% and about 15% of the
composition, as
discussed above. In one implementation, the impact modifier can be Cross-
linked
Poly(butyl methacrylate), with a Poly(methyl methacrylate) shell (Acrylic). In
another
-14-
CA 3067803 2019-11-29
implementation, the impact modifier can be Chlorinated Poly(ethylene) (CPE).
In some
implementations, the composition can include a fire retardant chemical (such
as the fire
retardant chemicals discussed above) in an amount that is between about 0.5%
and about
5% of the composition. In some implementations, the composition can include a
stabilizer in an amount that is between about 1% and about 2 % of the
composition. In
one implementation, the stabilizer can be Butyl Tin Thioglycolate. In
some
implementations, the composition can include a lubricant in an amount that is
between
about 2% and about 4% of the composition. In some implementations, the
composition
can include pigments in an amount between about 0% and about 5% of the
composition.
Thermal Expansion
[0059] A
panel assembly, such as the panel assembly 100; with the materials
disclosed herein for the panel 10, such as the materials for the substrate
layer(s) 11A
and/or capstock layer(s) 11B disclosed herein, advantageously has improved
resistance to
thermal expansion as compared with standard vinyl siding material. Whereas
standard
vinyl siding material has .a coefficient of linear thermal expansion (CLTE) of
approximately 3.4 x 10-5 (in/in/deg F) or 3.5 x 10-5 (in/in/deg F), a siding
panel having the
materials disclosed herein, such as the materials for the substrate layer(s)
11A and/or
capstock layer(s) 11B of the siding panel 10, advantageously has a CLTE
approximately
1/3rd lower than standard vinyl siding (e.g., approximately 2.33 x 10-5
in/in/deg F).
Samples of the siding panel 10 were tested in accordance with ASTM D696-16
achieved
an average CLTE of 2.04 x 10-5. (in/in/deg F) in the machine direction, with
certain
samples achieving an even lower average CLTE of 8.95 x 10-6 (in/in/deg F) in
the
machine direction. Two additional samples of the siding panel 10 with the
Acrylic
composition disclosed herein were tested in accordance with ASTM D696-16. One
sample achieved an average -CLTE of 2.22 x 10-5 (in/in/deg F), and the other
sample
achieved an average CLTE of 2.26 x 10-5 (in/in/deg F), resulting in an average
CLTE
measurement of 2.24 x 10-5 (in/in/deg F). The CLTE of the siding panel 10 can
be
reduced further when adhered (e.g., with one of the adhesives disclosed
herein) to a
backing panel (e.g., the backing panel 50 disclosed herein made of any of the
backing
panel materials disclosed herein). Accordingly, a panel assembly with the
materials
disclosed herein, such as the siding panel assembly 100 described above,
advantageously
-15-
CA 3067803 2019-11-29
has a CLTE of no more than approximately 2.33 x 10-5 (in/in/deg F) when
exposed to a
temperature of up to 180 degrees Fahrenheit.
[0060] One advantage provided by the improved thermal expansion
characteristics is the ability to provide a planar (e.g., flat) panel profile.
In contrast, prior
existing vinyl siding panels are not able to provide a flat profile due to
their much higher
CLTE, (approximately 1/3 higher) as discussed above. Another advantage
provided by
the improved thermal expansion characteristics is the ability to reduce the
width D of the
overhang portion or notch 17 of the siding panel assembly 100, as discussed
above, which
increases the area of the siding panel 10 that is attached (e.g., adhered to)
the backing
panel 50, thereby aiding in maintaining the planar (e.g., flat) profile of the
siding panel 10
during installation (e.g., because the overhang portion that can flex is
smaller). Another
advantage provided by the improved thermal expansion characteristics is the
ability to
reduce the spacing 49A between the openings or slots 49 in the nail hem 40,
allowing
additional openings or slots 49 for a given length to be provided in the nail
hem 40.
Further, the low thermal expansion advantageously allows the length of the
openings or
slots 49 to be shorter (e.g., approximately 1.06 inches as compared to 1.25
inches in
conventional siding panels), resulting in the nail hem 40 having additional
material and
therefore greater strength. The greater number of openings or slots 49 in the
nail hem 40
advantageously provides the siding panel 10 with improved wind load
resistance,
discussed further below. Another advantage provided by the improved thermal
expansion
characteristics is inhibiting (e.g., preventing) oil-canning of the siding
panel 10 since it is
subjected to less expansion and contraction during use.
Surface Distortion
[0061] Samples having the compositions described above for the
substrate
layer(s) 11A were tested in -accordance with ASTM 3679 Section 5.8. The
samples
withstood temperatures of up to 180 deg F without exhibiting surface
distortions or oil-
canning (e.g., bulges, waves, ripples, etc.).
[0062] Additionally, a high-altitude test was conducted of various
siding panel
samples having the materials disclosed herein, such as the materials for the
substrate
layer(s) 11A and/or capstock layer(s) 11B disclosed herein. Exposure testing
was
conducted over a month with the samples facing the sun in Prescott, Arizona at
tilt angles
of 90 degrees from the horizontal facing south. Six samples of a siding panel,
similar to
-16-
CA 3067803 2019-11-29
the siding panel 100, were exposed to ambient temperatures up to 90 degrees F
and
humidity levels of 10-37% over a period of one month. The siding panel samples
included a siding panel 10 with the CPE formulation described above, a backing
panel 50
of 0.85 lbfft3 density of GPS 5200+ foam material, and PUR adhesive between
the
backing panel 50 and siding panel 10. The high altitude tests reported maximum
temperature readings taken of the samples of up to 155 degrees F. None of the
samples
exhibited surface distortion or oil-canning (e.g., bulges, waves, ripples,
etc.) after thirty
days of exposure. Further, testing of samples of a siding panel, similar to
the siding panel
100, were exposed temperatures up to 210 degrees F in separate testing without
exhibiting surface distortion or oil-canning (e.g., bulges, waves, ripples,
etc.).
Fire Performance
[0063]
Various different samples having the compositions described above for
the substrate layer(s) 11A were tested for flame spread and smoke development.
The
results are shown in Table 1, below. Each test was conducted in accordance
with
Standard ANSPUL723, Tenth Edition, dated September 10, 2008 with revisions
through
August 12, 2013, "Test for Surface Burning Characteristics of Building
Materials",
(ASTM E84). Based on the National Fire Protection Association Life Safety
Code,
NFPA No. 101, a Class I (or A) material has a flame spread of 0-25 and smoke
developed
of 0-450, a Class II (or B) material has a flame spread of 26-75 and smoke
developed of
0-450, and a Class III (or C) material has a flame spread of 76-200 and smoke
developed
of 0-450. As shown in the results below, all samples tested met the Class A
fire rating. In
some implementations, the fire *retardant chemical promotes carbonaceous char
on
burning so that it does not exhibit char afterglow, which advantageously
decreases heat
released, oxygen consumption, production of carbon oxides and possible fire
spread.

Wind Load Testing
100641
Samples of the panel assembly 100 with the composition of the one or
more substrate layers 11A described above were also subjected to windload
testing to test
their windload resistance. Each test was conducted in accordance with ASTM
D5206-13.
All loads were negative pressure and held for thirty seconds. A 5 lbf/ft2 pre-
load was
applied before testing the samples to failure. The temperature during testing
was 18
Celsius. The results of such testing are provided in Table 2 below. As shown
in the test
results below, all samples of the panel assembly 100 did not exhibit damage
under
pressures of at least up to 55 lbf/ft2 pre-load, making them suitable for use
in in zones or
locations having a nominal design wind speed of up to 180 miles/hour (mph) for
category

Workability
[0065] Samples of the panel assembly 100 with the composition of the one or
more substrate layers 11 A described above were also subjected to impact
testing to test
their impact resistance. Each test was conducted in accordance with ASTM D4226-
16.
The results of such testing are provided in Table 3 below. As shown in the
results below,
all samples achieved a mean failure energy of greater than 35.0 in-lbf.

[0066] Advantageously, siding panel assemblies, such as the siding panel
assembly 100, have improved workability characteristics, including impact
resistance. For
example, the siding panel assemblies can be carried, handled, and installed
(e.g., cut with
tin snips during installation) even at relatively cold temperatures down to
about 8 deg F
without failing (e.g., chipping, breaking, shattering, disintegrating), such
as when struck
during installation (e.g., miss-hit with a hammer when nailing the nail hem 40
during
installation). Figure 5 shows a schematic partial view of one method of
assembling three
siding panel assemblies 100 coupled to each other in a row. Each of the siding
panel
assemblies 100A, 100B, 100C can have overhang portions 17A, 17B, each similar
to the
overhang portion 17 described above. When installed, the overhang portion of
one siding
panel can extend over the adjacent siding panel, whose overhand portion
extends under
the first siding panel. As shown in FIGS. 5A-C, the siding panel assembly 100A
has
overhang portion 17A that extends over a portion (e.g., straight edge portion)
of the siding
-20-
CA 3067803 2019-11-29
panel assembly 100B, and overhang portion 17B that extends over a portion
(e.g., straight
edge portion) of the siding panel assembly 100C.
Installation
[0067]
Figure 5 shows a schematic partial view of one method of assembling
three siding panel assemblies 100 coupled to each other in a row. In the
illustrated
implementation, each of the siding panel assemblies 100A, 100B, 100C can have
overhang portions or notches 17A; 17B, each similar to the overhang portion 17
described
above. When installed, the overhang portion of one siding panel can extend
over the
adjacent siding panel, whose overhand portion extends under the first siding
panel. As
shown in FIGS. 5A-5C, the siding panel assembly 100A has overhang portion 17A
that
extends over a portion (e.g., straight edge portion) of the siding panel
assembly 100B, and
an overhang portion 17B that extends over a portion (e.g., straight edge
portion) of the
siding panel assembly 100C.
[0068]
Figures 6A-6B show a schematic partial view of another method of
assembling adjacent siding panels 100D, 100E. In the illustrated
implementation, the
siding panels 100D, 100E are arranged so that their edges abut each other. As
described
above, the siding panel assemblies 100D, 100E exclude the overhang portion
(e.g.,
overhang portion or notch 17 in FIG. 1), allowing the full edge of the siding
panel 100D
to abut the full edge of the siding panel 100E. A clip 200 having openings 202
is
optionally placed across at least a portion of the nail hem 40 of both siding
panel
assemblies 100D, 100E, such that the openings 202 overlap with at least a
portion of the
openings 49. The nails are then .inserted through the overlapping openings
202, 49 to
thereby couple the clip 200 to the adjacent siding panel assemblies 100D,
100E.
Advantageously, the clip 200 is low profile and allows the next row of siding
panels to be
installed over the siding panel assemblies 100D, 100E, thereby concealing the
nail hem 40
and clip 200 (see FIG. 4B). Advantageously, the clip 200 holds the siding
panel
assemblies 100D, 100E tight (e.g., at their seam) and allows the siding panel
assemblies
100D, 100E to expand and contract (e.g., when exposed to hot or cold
temperatures) as
one integral panel assembly.
[0069]
FIGS. 7-7C shows installation of several siding panel assemblies
100A-100E, one above another, and coupled to each other as previously
described.
Advantageously, the design of the, siding panel assembly 100, as described
above, allows
-21-
CA 3067803 2019-11-29
each siding panel 100B-100E to be installed over the previous siding panel
assembly
100A-100D substantially vertically. That is, once the first siding panel
assembly 100A is
installed (e.g., nails nailed through the nail hem 40 to mount it to the wall
W, the next
siding panel assembly 100B can be placed against the wall W and slid down
(e.g.,
dropped down) onto the top of the fist panel assembly 100A (e.g., so that the
buttlock
portion 30 of the second siding panel assembly 100B extends over and couples
to the U-
shaped wall portion 24 of the first siding panel assembly 100A). This
facilitates
installation of the siding panel assemblies and does not require each siding
panel
assembly to be installed at an angle and then snapped into place over the
previous siding
panel assembly.
[0070] As discussed above, the overhang portion or notch 17 has a
width L3
of approximately 0.75 inches, which advantageously reduces the amount of the
panel 10
that is not supported by the backing panel 50. An adjacent panel assembly 100
can be
positioned so that its end extends under the overhang portion or notch 17. In
one
implementation, said end of the adjacent panel assembly 100 can be up to about
1/4 inches
apart from the backing panel -50 of the adjacent panel assembly 100. In
contrast, typical
vinyl siding panel assemblies have a notch of about 1.5 inches and require
that the
adjacent siding panel extend underneath the notch and between the siding panel
and
insulation material of the adjacent panel, which causes the exterior panel to
bulge out.
[0071] FIGS. 8A-8B shows a siding panel assembly 100'. Some of the
features of the siding panel assembly 100' are similar to features in the
siding panel
assembly 100 of FIGS. 1-4. Thus, references numerals used to designate the
various
components of the siding panel assembly 100 are identical to those used for
identifying
the corresponding components of the siding panel assembly 100' in FIGS. 8A-8B,
except
that a " ' "is added to the numerical identifier. Therefore, the structure and
description
for the various components of the siding panel assembly 100 in FIGS. 1-4 is
understood
to also apply to the corresponding components of the siding panel assembly
100' in FIGS.
8A-8B, except as described below.
[0072] The siding panel assembly 100' is a vertical siding panel
(e.g., Board
and Batten) that can be installed vertically on a wall. The siding panel
assembly 100' can
have a siding panel 10' and optionally have a backing panel 50' made of the
materials
discussed above for the siding panel assembly 100' and substantially the same
CLTE, fire
performance, wind performance and/or impact performance. The siding panel
assembly
-22-
CA 3067803 2019-11-29
100' can have a width W1 of about twelve inches, with a course or face portion
12' with a
forward facing (e.g., outer facing) surface 12a' approximately 10 inches in
width W2.
However, the width W1 of the siding panel assembly 100' and width W2 of the
course or
face portion 12' of the siding panel 10 can have other values. Additionally,
the siding
panel assembly 100' can have a low profile and an overall thickness H (from
the wall on
which it's mounted) of no more than about 3/4 inches, allowing the siding
panel assembly
100' to be used with standard accessories during installation.
[0073] FIGS. 9-9A shows a siding panel assembly 100". Some of the
features
of the siding panel assembly 100" are similar to features in the siding panel
assembly 100
of FIGS. 1-4. Thus, references numerals used to designate the various
components of the
siding panel assembly 100 are identical to those used for identifying the
corresponding
components of the siding panel assembly 100" in FIGS. 9-9A, except that a" "
"is added
to the numerical identifier. Therefore, the structure and description for the
various
components of the siding panel assembly 100 in FIGS. 1-4 is understood to also
apply to
the corresponding components of the siding panel assembly 100" in FIGS. 9-9A,
except
as described below.
[0074] The siding panel 100" can have a siding panel 10" and
optionally have
a backing panel 50". The siding panel assembly 100" can have a planar (e.g.,
flat) profile
with a V groove between panels 100", and can be horizontally installed. The
siding
panel assembly 100' can have a siding panel 10' and optionally have a backing
panel 50'
made of the materials discussed above for the siding panel assembly 100' and
substantially the same CLTE, fire performance, wind performance and/or impact
performance. Additionally, the siding panel assembly 100" can have a low
profile and an
overall thickness H (from the wall on which it's mounted) of no more than
about 3/4
inches, allowing the siding panel assembly 100' to be used with standard
accessories
during installation.
[0075] Advantageously, the siding panel assembly 100 is low profile
and has a
maximum thickness or projection' H (from a wall it's installed on) of less
than about 3/4
inches, as discussed above. In one implementation, the maximum thickness or
projection
H (from a wall it's installed upon) is about 0.72 inches. This allows
installation of the
siding panel assembly 100 using standard readily available accessories (e.g.,
J-channel,
inside corner post, outside corner post, cellular PVC trim, etc.).

[0076] FIGS. 10A-10C show a trim accessory 400 that can be used
(e.g., for
inside corner posts, outside corner posts) to receive siding panel assemblies,
such as the
siding panel assembly 100 described above. The trim accessory 400 optionally
has a
substantially planar (e.g., flat) front surface 410 and a stepped rear surface
defined by
planar portions 420A, 420B, 420C separated by step portions 422B, 422C, so
that the rear
surface transitions from one planar portion 420A to another planar portion
420B via a
stepped portion 422B. The planar portions 420A, 420B, 420C can be angled
relative to
the front surface 410 by approximately the same amount as the course surface
12a is
relative to the bottom surface 52 of the backing panel 50. Additionally, the
planar
portions 420A, 420B, 420C optionally have a length approximately the same as
the length
L of the course surface 12a. Advantageously, the trim accessory 400 fits over
the
assembled siding panel assemblies 100A, 100B, 100C (as shown in FIG. 11) such
that
shadow areas at the ends of the siding panels (e.g., due to gaps between the
trim accessory
and siding panels) are reduced or eliminated. This structure also inhibits
(e.g., prevents)
intrusion of rain, wind, dirt, debris, insects or other contaminants between
the trim
accessory 400 and siding panels 100A, 100B, 100C, inhibiting such contaminants
from
getting behind the siding panels 100A, 100B, 100C. in another implementation,
a seal
(e.g., seal strip) can be provided between the rear surface of the trim
accessory 400 and
the siding panel assemblies 100A, 100B, 100C to further seal the space between
them.
[0077] While certain embodiments of the invention have been
described, these
embodiments have been presented by way of example only, and are not intended
to limit
the scope of the disclosure. Indeed, the novel methods and systems described
herein may
be embodied in a variety of other forms. Furthermore, various omissions,
substitutions
and changes in the systems and methods described herein may be made without
departing
from the spirit of the disclosure. The accompanying claims and their
equivalents are
intended to cover such forms or modifications as would fall within the scope
and spirit of
the disclosure. Accordingly, the scope of the present inventions is defined
only by
reference to the appended claims.
[0078] Features, materials, characteristics, or groups described in
conjunction
with a particular aspect, embodiment, or example are to be understood to be
applicable to
any other aspect, embodiment or example described in this section or elsewhere
in this
specification unless incompatible therewith. All of the features disclosed in
this
specification (including any accompanying claims, abstract and drawings),
and/or all of
-24-
CA 3067803 2019-11-29
the steps of any method or process so disclosed, may be combined in any
combination,
except combinations where at least some of such features and/or steps are
mutually
exclusive. The protection is not restricted to the details of any foregoing
embodiments.
The protection extends to any novel one, or any novel combination, of the
features
disclosed in this specification (including any accompanying claims, abstract
and

method or
process so disclosed.
[0079] Furthermore, certain features that are described in this
disclosure in the
context of separate implementations can also be implemented in combination in
a single
implementation. Conversely, various features that are described in the context
of a single
implementation can also be implemented in multiple implementations separately
or in any
suitable subcombination. Moreover, although features may be described above as
acting
in certain combinations, one or more features from a claimed combination can,
in some
cases, be excised from the combination, and the combination may be claimed as
a
subcombination or variation of a subcombination.
[0080] Moreover, while operations may be depicted in the drawings
or
described in the specification in a particular order, such operations need not
be performed
in the particular order shown or in sequential order, or that all operations
be performed, to
achieve desirable results. Other operations that are not depicted or described
can be
incorporated in the example methods and processes. For example, one or more
additional
operations can be performed before, after, simultaneously, or between any of
the
described operations. Further, the operations may be rearranged or reordered
in other
implementations. Those skilled in the art will appreciate that in some
embodiments, the
actual steps taken in the processes illustrated and/or disclosed may differ
from those
shown in the figures. Depending on the embodiment, certain of the steps
described above
may be removed, others may be added. Furthermore, the features and attributes
of the
specific embodiments disclosed above may be combined in different ways to form
additional embodiments, all of which fall within the scope of the present
disclosure.
Also, the separation of various system components in the implementations
described
above should not be understood as requiring such separation in all
implementations, and it
should be understood that the described components and systems can generally
be
integrated together in a single product or packaged into multiple products.

[0081] For purposes of this disclosure, certain aspects,
advantages, and novel
features are described herein. Not necessarily all such advantages may be
achieved in
accordance with any particular embodiment. Thus, for example, those skilled in
the art
will recognize that the disclosure may be embodied or carried out in a manner
that
achieves one advantage or a group of advantages as taught herein without
necessarily
achieving other advantages as. may be taught or suggested herein.
[0082] Conditional language, such as "can," "could," "might," or
"may,"
unless specifically stated otherwise, or otherwise understood within the
context as used, is
generally intended to convey that certain embodiments include, while other
embodiments
do not include, certain features, elements, and/or steps. Thus, such
conditional language
is not generally intended to imply that features, elements, and/or steps are
in any way
required for one or more embodiments or that one or more embodiments
necessarily
include logic for deciding, with or without user input or prompting, whether
these
features, elements, and/or steps are included or are to be performed in any
particular
embodiment.
[0083] Conjunctive language such as the phrase "at least one of X,
Y, and Z,"
unless specifically stated otherwise, is otherwise understood with the context
as used in
general to convey that an item, term, etc. may be either X, Y, or Z. Thus,
such
conjunctive language is not generally intended to imply that certain
embodiments require
the presence of at least one of X, at least one of Y, and at least one of Z.
[0084] Language of degree used herein, such as the terms
"approximately,"
"about," "generally," and "substantially" as used herein represent a value,
amount, or
characteristic close to the stated = value, amount, or characteristic that
still performs a
desired function or achieves a desired result. For example, the terms
"approximately",
"about", "generally," and "substantially" may refer to an amount that is
within less than
10% of, within less than 5% of, within less than 1% of, within less than 0.1%
of, and
within less than 0.01% of the stated amount. As another example, in certain
embodiments, the terms "generally parallel" and "substantially parallel" refer
to a value,
amount, or characteristic that departs from exactly parallel by less than or
equal to 15
degrees, 10 degrees, 5 degrees, 3 degrees, 1 degree, or 0.1 degree.
[0085] The scope of the present disclosure is not intended to be
limited by the
specific disclosures of preferred embodiments in this section or elsewhere in
this
specification, and may be defined by claims as presented in this section or
elsewhere in
-26-
CA 3067803 2019-11-29
this specification or as presented in the future. The language of the claims
is to be
interpreted broadly based on the language employed in the claims and not
limited to the
examples described in the present specification or during the prosecution of
the
application, which examples are to be construed as non-exclusive.
[0086] Of
course, the foregoing description is that of certain features, aspects
and advantages of the present invention, to which various changes and
modifications can
be made without departing from the spirit and scope of the present invention.
Moreover,
the devices described herein need not feature all of the objects, advantages,
features and
aspects discussed above. Thus, for example, those of skill in the art will
recognize that
the invention can be embodied or carried out in a manner that achieves or
optimizes one
advantage or a group of advantages as taught herein without necessarily
achieving other
objects or advantages as may be taught or suggested herein. In addition, while
a number
of variations of the invention have been shown and described in detail, other
modifications and methods of use, which are within the scope of this
invention, will be
readily apparent to those of skill in the art based upon this disclosure. It
is contemplated
that various combinations or subcombinations of these specific features and
aspects of
embodiments may be made and still fall within the scope of the invention.
Accordingly, it
should be understood that various features and aspects of the disclosed
embodiments can
be combined with or substituted for one another in order to form varying modes
of the
